Communicating location specific emergency information to a mobile device

ABSTRACT

An occurrence of an emergency situation pertinent to people presently located within a venue can be identified. Responsive to identifying the emergency situation pertinent to the people located within the venue, an emergency alert can be automatically communicated to a first mobile device. The emergency alert can provide contextual information pertaining to the emergency situation, wherein the contextual information indicates precautions to be observed by the user. The emergency alert can be configured to be presented by the first mobile device to the user to alert the user to the emergency situation.

BACKGROUND

The present invention relates to mobile communications and, more particularly, to emergency related mobile communications.

Emergency procedures, exit locations, and other potential lifesaving information oftentimes are provided in commercial buildings, but are usually accessible as diagrams or depictions, posted in limited places, or as videos posted in limited places at limited times. As an example, in certain municipalities, public transportation vehicles, such buses, taxis and airplanes, are required to present to passengers emergency exit procedures using schematic images or videos. Such schematic images and videos oftentimes lack detailed explanation and are general in nature. In addition, they usually do not present a step-by-step algorithm customized based on the specific location, situation or emergency. Moreover, passengers do not necessarily have procedures readily available if needed. For example, a hotel may post an emergency exit schematic diagram in hotel rooms, but once customers leave their hotel rooms, they may not find any other emergency exit diagrams while attempting to leave the hotel during an emergency.

U.S. Pat. No. 7,098,787 discloses “[a] mobile device receives proximity location information from at least one location identification beacon. A user of the mobile device dials an emergency telephone number when an emergency occurs. Dialing the emergency telephone number enables the proximity location information to be transmitted to an emergency call center.” During an emergency, however, users, may find it distracting and cumbersome to have to dial an emergency telephone number.

U.S. Pat. No. 8,755,767 discloses a “method and system provide a current physical geographic location for a mobile device (e.g., building address, a building floor, a room on a building floor, campus, enterprise, city, state, region, country, continent, etc.), in an emergency situation such as an accident, fire, terrorist attack, military incident, etc. and forward the physical geographic location to a legacy 911 network or a Emergency Services IP networks (ESInet).” Such operation, however, does not help guide people safely out of a structure.

U.S. Pat. No. 7,720,431 discloses a “mobile wireless system (10) includes a transmitter such as a satellite (18) that broadcasts wireless signals such as boundaries for specific areas to a mobile receiving device (22). Mobile receiving device (22) may include an antenna (26) and a mobile receiving device (28). A locating receiver (50) is used to generate locating signals so that a determination may be made to the location of the mobile receiving device. When the location is outside an area of interest the area of interest may be extended to provide services to the mobile device. Emergency information is broadcast to a first area. An emergency announcement indicator is also broadcast into a first area and an area outside the first area. The location of the mobile receiving device is compared to the first area and the emergency information is displayed when the location is within the first area.” Thus, a user must be located in proximity of where the emergency announcement indicator is broadcast in order to receive the emergency announcement.

DETAILED DESCRIPTION

The present invention relates to mobile communications and, more particularly, to emergency related mobile communications. In accordance with the arrangements disclosed herein, responsive to identifying an occurrence of an emergency situation pertinent to people presently located within a venue, a system can communicate to a user's mobile device information pertinent to the emergency situation. In illustration, the system can automatically communicate to the mobile device an emergency alert providing contextual information pertaining to the emergency situation. The mobile device can present the emergency alert to the user. Further, the system can determine a present location of a mobile device within a venue, and communicate to the mobile device location specific emergency information describing an emergency plan for exiting the venue from the present location to an exit. The mobile device can present the emergency plan to the user. Accordingly, rather than having to look for exit signs to follow to exit the venue, the user can follow a route provided by the emergency plan. This can help the user to exit the structure more quickly.

FIG. 1 is a block diagram illustrating an example of a communication system 100. The communication system 100 contains at least one communication network 110. The communication network 110 is the medium used to provide communications links between various devices and data processing systems connected together within communication system 100. The communication network 110 may include connections, such as wire, wireless communication links, or fiber optic cables. The communication network 110 may be implemented as, or include, any of a variety of different communication technologies such as a Wide Area Network (WAN), a Local Area Network (LAN), a wireless network, a mobile or cellular network, a Virtual Private Network (VPN), the Internet, the Public Switched Telephone Network (PSTN), or the like.

The communication system 100 also can include an emergency notification system 120 and a plurality of beacons 130, 132, 134, each of which may couple to the communication network 110. The communication system 100 also can include a plurality of mobile devices 140, 145. In one aspect of the present arrangements, one or more of the beacons 130-134 can be implemented as wireless access points, wireless routers, microcells or the like, and the mobile devices 140, 145 can couple to the communication network 110 via the beacons 130-134 to both receive and transmit messages via the communication network 110. In another aspect, the beacons 130-134 can be implemented as devices configured to transmit radio frequency (RF) and/or infrared (IR) messages that are detectable by one or more of the mobile devices 140, 145, but the beacons 130-134 need not be configured to relay messages transmitted by the mobile devices 140, 145 to the communication network 110.

The emergency notification system 120 may be implemented as one or more data processing systems (e.g., servers), each including at least one processor and memory, executing suitable operational software to support communication of emergency notifications to one or more of the mobile devices 140, 145. For example, the emergency notification system 120 can host an emergency notification application 125.

One or more of the mobile devices 140, 145 can include a respective emergency notification client 150, 155. An emergency notification client 150, 155 can be a stand-alone application executing on a respective mobile device 140, 145, or integrated into an operating system or other application executing on the respective mobile device 140, 145. By way of example, the emergency notification client 150 can be implemented as a service executing on the mobile device 140. In one arrangement, for example an arrangement in which the beacons 130-134 are wireless access points or wireless routers, the emergency notification client 150 can detect the mobile device 140 establishing network presence on a network (e.g., a subnet) to which the beacons 130-134 provides network access, and monitor messages received by the mobile device 140 via the wireless access points or wireless routers. In another arrangement, the emergency notification client 150 can monitor beacon signals generated by the beacons 130-134 and received by the mobile device 140. Regardless, responsive to receiving a message or beacon signal indicating an occurrence of an emergency situation pertinent people presently located within a venue, the emergency notification client 150 can implement any number of various processes responsive to such messages/signals, as will be described. The venue can be a building, a hotel, a motel, a stadium, a store, a shopping mall, an aircraft, a vehicle (e.g., a bus), a watercraft, an amusement park or the like.

In operation, the emergency notification system 120 can detect an occurrence of an emergency situation pertinent people presently located within a venue. For example, the emergency notification system 120 can detect a signal from one or more fire alarms indicating that a fire is present in the venue, detect a signal from one or more seismic sensors indicating that the venue has experienced an earthquake, detect a signal from one or more weather sensors indicating that a tornado is present in proximity to the venue, detect a signal from one or more acoustic sensors indicating gunshots are fired in the venue, detect a signal from one or more emergency alarms (e.g., fire alarms, silent alarms, etc.), or the like. In another example, the emergency notification system 120 can monitor information generated by news and/or social media websites, emergency response services, etc., and detect information that indicates an occurrence of emergency situation pertinent people presently located within a venue.

Responsive to detecting an occurrence of an emergency situation pertinent to people presently located within the venue, the emergency notification system 120 can communicate to the mobile device 140, as well as other mobile devices, an emergency alert 160 via one or more of the beacons 130-134. The emergency alert 160 can be communicated to the mobile device 140 via one or more of the beacons 130-134, and can be configured to be presented by the mobile device 140 to the user to alert the user to the emergency situation, for example via a display and/or output audio transducer of the mobile device 140. Accordingly, the mobile device 140 can present the emergency alert 160 to the user. The emergency alert 160 can provide contextual information pertaining to the emergency situation. The contextual information can, for example, indicate the nature of the emergency, actions to be taken by the user, precautions to be observed by the user, and the like.

In one arrangement, the emergency notification client 150 can continually monitor for beacons signals and/or messages. Responsive to detecting the emergency alert 160, the emergency notification client 150 can automatically present the emergency alert 160 on the mobile device 140. If the mobile device 140 presently is in sleep mode, the emergency notification client 150 can automatically take the mobile device 140 out of sleep mode to present the emergency alert 160. In another arrangement, the emergency notification client 150 can present the emergency alert 160 responsive to detecting a user input on the mobile device 140. For instance, the emergency notification client 150 can present the emergency alert 160 responsive to the user launching a web browser on the mobile device 140. In a further arrangement, responsive to the beacon 130 detecting the mobile device 140 attempting to access the communication network 110 via the beacon 130, the beacon 130 can intercept an HTTP request communicated by the mobile device 140 and re-direct the HTTP request to a particular website hosted by the emergency notification system 120 presenting the emergency alert 160. Such website can respond to the HTTP request by communicating one or more HTTP responses that include the emergency alert 160, and the web browser on the mobile device 140 can render the emergency alert 160 on the mobile device 140.

Further, in lieu of or in addition to the emergency alert 160, responsive to detecting the occurrence of the emergency situation, the emergency notification system 120 can communicate to the mobile device 140, as well as other mobile devices, location specific emergency information 165 via one or more of the beacons 130-134. The location specific emergency information 165 also can be configured to be presented by the mobile device 140 to the user, for example via a display and/or output audio transducer of the mobile device 140. Accordingly, the mobile device 140 can present the location specific emergency information 165 to the user. The location specific emergency information 165 can provide to the user emergency information that is specific to the user's location within the venue. For example, the location specific emergency information 165 can include one or more diagram or images providing a route for the user to exit the venue, one or more videos showing the route for the user to exit the venue, or the like. Such diagram(s), image(s) and/or video(s) also can present to the user contextual information pertaining to the emergency situation.

The user's location within the venue can be determined in any suitable manner. In one arrangement, the emergency notification system 120 can store in a computer-readable storage medium, which may be contained within the emergency notification system 120 or otherwise coupled to the emergency notification system 120, information indicating the location of each of the beacons 130-134. In this arrangement, the location specific emergency information 165 can be generated for each of the beacons 130-134, and the emergency notification system 120 can communicate to each of the beacons 130-134 respective location specific emergency information 165 to be communicated to mobile devices that are located in proximity to the respective beacons 130-134. For example, if the mobile device 140 is located proximate to the beacon 130, the mobile device 140 can receive the location specific emergency information 165 from the beacon 130. In some cases the mobile device 140 may receive signals from more than one beacon 130-134. In such cases, the emergency notification client 150 can be configured to receive and process the signal from the beacon 130 having the highest strength, and present to the user the location specific emergency information 165 contained in that signal.

In another arrangement, for example an arrangement in which one or more of the beacons 130-134 are wireless access points or wireless routers, the emergency notification system 120 can determine a present location of the mobile device 140 based on which beacon 130-134 the mobile device 140 is communicatively linked, or based on a position of the mobile device 140 determined by a global positioning system (GPS) receiver. In illustration, the mobile device 140 can include a GPS receiver and periodically communicate to the emergency notification system 120 messages indicating the present location of the mobile device 140. The emergency notification system 120 also can receive information from the beacons 130-134 relating to a strength of signals communicated between the beacons 130-134 and the mobile device 140 and, based on the strength of such signals, perform trilateration to determine the present location of the mobile device 140. Regardless, responsive to determining the present location of the mobile device 140 within the venue, the emergency notification system 120 can communicate to the mobile device 140 the location specific emergency information 165 that is based on the mobile device's present location.

Regardless of how the user's location within the venue is determined, the location specific emergency information 165 can include information that is specific to the present location of the mobile device 140, and thus the user. In illustration, the location specific emergency information 165 can include an emergency plan for exiting the venue from a present location of the mobile device 140 within the venue. For instance, the location specific emergency information 165 can safely guide the user from the present location to an exit of the venue. More particularly, the emergency notification system 120 can configure the location specific emergency information 165 to present to the user a route to safely get from the present location to the exit. The route can be predefined for the present location of the mobile device 140, or the emergency notification application 125 can dynamically determine the route by processing digitized information indicating passageways within the venue (e.g., doorways, openings, hallways, staircases, elevators, escalators, rooms, and the like), nature of the emergency situation, etc.

By way of example, if the emergency situation is a fire in the south side of the venue, the emergency notification system 120 can determine that the route should not include passageways in the south side of the venue. Hence, the emergency notification system 120 can automatically process information related to the emergency situation and information relating to the venue to determine a route from the present location to an exit that does not traverse through the south side of the venue, and that route can be communicated in the location specific emergency information 165. Such route can be considered to be safe for the user since it does not route the user through the portion of the venue where the fire is located. Similarly, if the emergency notification system 120 detects gun shots fired in the south side of the venue, or detects that a stairway is collapsed in the south side of the venue (e.g., due to an earthquake, tornado, hurricane, explosion, or the like), the emergency notification system 120 can automatically process such information to determine a safe route to get the user from the present location to the exit.

In one aspect of the present arrangements, for example an arrangement in which the user is an employee or contractor working in a venue that is a secured facility, the emergency notification system 120 also can store, or otherwise access (e.g., from an active directory) user security profiles and information indicating user level of security clearances that are required for users to access various passageways in the venue.

By way of example, assume that the secured facility includes various passageways that are restricted to users having a particular level of security clearance. The user of the mobile device 140 may not have a level of security clearance required to access all passageways in the secured facility. Thus, when determining the route from the present location of the mobile device 140 to an exit, the emergency notification system 120 can demine a level of security clearance assigned to the user and determine a route that does not require the user to be assigned a level of security clearance that is higher than that level of security clearance in order for the user to traverse the route. In this regard, the location specific emergency information 165 generated by the emergency notification system 120 can describe a route that does not include passageways for which the user does not have an assigned level of security clearance to enter. Such an arrangement can ensure that the user is able to safely reach an exit without being blocked by a door to a passage way for which the user does not have the proper level of security clearance to access.

In another aspect of the present arrangements, the location specific emergency information 165 generated by the emergency notification system 120 can describe a route that includes only passageways that do not require the user to be assigned a level of security clearance whatsoever. In yet another aspect of the present arrangements. The emergency notification system 120 can interface with one or more security systems in the venue to disable security requirements otherwise required for users to enter various secure passageways within the venue. For example, the emergency notification system 120 can interface with the security system(s) to unlock doors or configure the doors to become unlocked for any user presenting a user identification that is recognized by the security system(s) and/or the emergency notification system 120. Such an arrangements can ensure that the user is not blocked from accessing passage ways the user may need to traverse to safely reach the exit.

In another aspect of the present arrangements, rather than the emergency notification system 120 providing the emergency alert 160 and/or location specific emergency information 165, the beacon 130 can statically store the emergency alert 160 and/or location specific emergency information 165. Responsive to the beacon 130 receiving a message or other signal from the emergency notification system 120 indicating the occurrence of the emergency situation, the beacon 130 can begin transmitting the emergency alert 160 and/or location specific emergency information 165 to be received by mobile devices, such as the mobile device 140. The beacon 130 can repeatedly transmit the emergency alert 160 and/or location specific emergency information 165 until the beacon 130 receives a message or other signal to stop transmitting such information.

In another aspect of the present arrangements, the beacon 130 can receive updates to the emergency alert 160 and/or location specific emergency information 165, for example from the emergency notification system 120 and/or one or more other systems, and the beacon 130 can update the emergency alert 160 and/or location specific emergency information 165 accordingly. Responsive to updating the emergency alert 160 and/or location specific emergency information 165, the beacon 130 can begin transmitting the updated emergency alert 160 and/or location specific emergency information 165 in lieu of the previous emergency alert 160 and/or location specific emergency information 165.

In further aspects of the present arrangements, the mobile device 140 can be configured to share the emergency alert 160 and/or the location specific emergency information 165 received from the emergency notification system 120 with one or more other mobile devices, such as the mobile device 145. For example, the emergency notification client 150 can be configured to detect reception of the emergency alert 160 and/or the location specific emergency information 165 by the mobile device 140 and share such with the mobile device 145. In illustration, responsive to receiving the emergency alert 160 and/or the location specific emergency information 165, the mobile device 140 can establish an ad hoc communication link with the mobile device 145, for example a WiFi® communication link, a mesh network communication link and/or a personal area network (PAN) communication link.

In such an arrangement, the emergency notification client 150 can be configured to, in response to the mobile device 140 receiving the emergency alert 160 and/or the location specific emergency information 165, automatically initiate the mobile device 140 to broadcasts signals requesting communication links to other mobile devices, such as the mobile device 145. The emergency notification client 155 executing on the mobile device 145 can be configured to recognize such communication signals generated by the mobile device 140 and automatically initiate processes on the mobile device 145 to establish an ad hoc communication link between the mobile device 140 and the mobile device 145. Responsive to the ad hoc communication link being established, the mobile device 140 can communicate to the mobile device 145 the emergency alert 160 and/or the location specific emergency information 165. Moreover, the mobile device 145 can function as a hotspot, relaying communications exchanged between the mobile device 145 and the beacon 130, or between the mobile device 145 and the communication network 110.

In accordance with the above example, the mobile device 145 can receive from the mobile device 140 the emergency alert 160 and/or the location specific emergency information 165 even though the mobile device 145 may not be able to receive signals and/or messages from the beacons 130-134, which may be due to any number of reasons. For example, the WiFi® transceiver and/or cellular network transceiver of the mobile device 145 may be unable to communicate with the beacons 130, 134, while the PAN transceiver still is operative. Nonetheless, the mobile device 145 may be able to receive the emergency alert 160 and/or the location specific emergency information 165 via the PAN transceiver.

In a further arrangement, the beacon 130 can receive a distress signal from the mobile device 145, for example via a mesh network established among the mobile device 145 and the mobile device 140 and other mobile devices. Responsive to receiving the distress signal from the mobile device 145, the beacon 130 can communicate the distress signal to the mobile device 140 and/or one or more other beacons 132, 134 for sharing with other mobile devices. The emergency notification client 150 executing on the mobile device 140 can present the distress signal to the user of the mobile device 140. Accordingly, the user of the mobile device 140 can take action to aid the user of the mobile device 145.

Additionally, the beacons 130-134 can be members of the mesh network established among the mobile devices 140, 145, or the beacons 130-134 can form their own mesh network. Thus, if one or more of the beacons 130-134 lose connectivity to the communication network 110, other beacons can act as relays for the affected beacons. In illustration, if the beacon 130 loses connectivity to the communication network 110, the beacon 132 can serve to relay communications between the beacon 130 and the communication network 110.

FIG. 2 is a flow chart illustrating an example of a method 200 of communicating to a mobile device location specific emergency information. At step 205, an occurrence of an emergency situation pertinent to people located within the venue can be identified. At step 210, responsive to identifying the emergency situation pertinent to the people located within the venue, an emergency alert and location specific emergency information can be automatically communicated to a first mobile device. The location specific emergency information can describe an emergency plan for exiting the venue from a present location of the first mobile device within the venue, wherein the location specific emergency information is configured to be presented by the first mobile device to a user of the first mobile device to safely guide the user from the present location to an exit of the venue. At step 215, emergency propagation information can be automatically communicated to the first mobile device. The emergency propagation information can be configured to be processed by the first mobile device to initiate the first mobile device to establish a communication link with at least a second mobile device and communicate from the first mobile device to the second mobile device the emergency alert and the location specific emergency information.

FIG. 3 is a block diagram illustrating example architecture for the emergency notification system 120 of FIG. 1. The emergency notification system 120 can include at least one processor 305 (e.g., a central processing unit) coupled to memory elements 310 through a system bus 315 or other suitable circuitry. As such, the emergency notification system 120 can store program code within the memory elements 310. The processor 305 can execute the program code accessed from the memory elements 310 via the system bus 315. It should be appreciated that the emergency notification system 120 can be implemented in the form of any system including a processor and memory that is capable of performing the functions and/or operations described within this specification that are performed by the emergency notification system 120. For example, the emergency notification system 120 can be implemented as one or more hardware servers.

The memory elements 310 can include one or more physical memory devices such as, for example, local memory 320 and one or more bulk storage devices 325. Local memory 320 refers to random access memory (RAM) or other non-persistent memory device(s) generally used during actual execution of the program code. The bulk storage device(s) 325 can be implemented as a hard disk drive (HDD), solid state drive (SSD), or other persistent data storage device. The emergency notification system 120 also can include one or more cache memories (not shown) that provide temporary storage of at least some program code in order to reduce the number of times program code must be retrieved from the bulk storage device 325 during execution.

One or more network adapters 330 can be coupled to emergency notification system 120 to enable the emergency notification system 120 to become coupled to other systems, computer systems, remote printers, and/or remote storage devices through intervening private or public networks. Modems, cable modems, transceivers, and Ethernet cards are examples of different types of network adapters 330 that can be used with the emergency notification system 120.

As pictured in FIG. 3, the memory elements 310 can store components of the emergency notification system 120, for example an operating system 335 and the emergency notification application 125 of FIG. 1. Being implemented in the form of executable program code, the operating system 335 and the emergency notification application 125 can be executed by the processor 305. For example, the processor 305 can execute the emergency notification application 125 within a computing environment provided by the operating system 335 in order to perform the processes described herein that are performed by the emergency notification system 120.
